Abstract
The present invention relates to a method for producing an interim sheet, the method comprising the steps of: k) providing at least a first sheet material impregnated with a first thermosetting resin, and a second sheet material impregnated with a second thermosetting resin; and, l) pressing the first and second sheet materials together, at a temperature of between 60° C. and 115° C., for between 40 and 130 minutes, such that the first and second thermosetting resins become liquid, and pressing with a first sufficient pressure such that the first and second sheet materials fuse to form an interim sheet without fully curing the first and second thermosetting resins such that the first and second thermosetting resins can flow again when heated.
